Determinación de la composición química de materias primas utilizadas en la alimentación en aves.

Abstract

The present research work aimed to determine the chemical composition of raw materials used in feeding birds that was carried out at Escuela Superior Politécnica de Chimborazo, Ciencias Pecuarias Faculty, Animal Nutrition and Bromatology Laboratory. An experimental field and laboratory methodology was used since the raw material (corn, soy cake and rice powder) was collected in quantities to be analyzed in the laboratory all the characteristics under study proceeding with the application of with 3 repetitions in each of the raw materials used in 4 different places where moisture, ash, crude protein, crude fiber, ethereal extract, Nitrogen-free extract and metabolizable energy by means of proximal analysis with the Weende method of corn, soy cake and powder. In the experimental results showed significant differences to (p<0.05) in humidity (0.0004%) and EE (0.0271%) in corn, however, in soybean cake the difference in ash was presented with 0.0004%. Finally, in the rice powder, there were differences in humidity with one (0.0005%) and fiber (0.0139%) in the four cantons. It is concluded that the chemical composition of corn there are significant differences in moisture and E.E, in soy cake there are significant differences in ash and in rice powder we have differences in moisture and fiber. It is recommended to evaluate the raw materials of this study in different climatic floors or areas of interest of livestock production replicating this procedure in different raw materials useful for feeding birds in order to have a database at national level.
